Dec.24 (GMM) Serbian businessman Zoran Stefanovic's interest in the Toyota formula one team stepped up a gear last week.

His outfit Stefan GP hopes to make its grand prix debut either next year or in 2011, and a recent visit to Toyota's Cologne headquarters has now been confirmed.

It has been reported that, because not bound by the Concorde Agreement, Stefan GP can take over Toyota's TF110 (2010) car design and test it at leisure, unless a vacancy on the 2010 grid arises and the team can immediately step into the sport.

"Mr Stefanovic was in Toyota Motorsport in Cologne," Stefan GP confirmed. "There was (a) meeting with Mr (Yoshiaki) Kinoshita and other leading people."

Those other leading people included John Howett, and Toyota's F1 technical director Pascal Vasselon.

"It was very productive session and further cooperation are detailed," Stefan GP added.
